I certainly am relieved and overjoyed to see that 167th episode will be dedicated to Erza, manga was unacceptably lazy with it. The finale of 166 and the preview of 167 hyped me so much that I felt like I drank 10 cups of coffee just when I was about to go to bed.
Self-note: Don't ever watch Erza before sleep!
The arc is going great overall, best arc so far IMO. Fights, characters, pacing, all is above FT standards. I hope they will finish it completely before putting any fillers.
